The prism pattern of rat molar enamel: a scanning electron microscope study
The American Journal of Anatomy
|June 1, 1979
Summary
Rat molar enamel exhibits variable prism patterns, differing significantly from incisor enamel. These findings offer insights into amelogenesis and factors influencing ameloblast movement.
Area of Science:
- Dental Microscopy
- Developmental Biology
- Histology
Background:
- Rat incisor enamel exhibits a well-defined prism pattern.
- Understanding enamel structure is crucial for amelogenesis research.
Purpose of the Study:
- To investigate the prism pattern variability in rat molar enamel.
- To compare molar enamel structure with rat incisor enamel.
- To elucidate factors controlling ameloblast movement during amelogenesis.
Main Methods:
- Enamel sectioning along various planes.
- Scanning Electron Microscopy (SEM) observation of etched surfaces.
Main Results:
- Rat molar enamel prism patterns are highly variable, unlike incisor enamel.
- Prism decussation, when present, is uniserial lamellar type and predominantly in cervical enamel.
- Interprismatic substance shows distinct radial sheets in inner enamel and honeycomb in outer enamel.
Conclusions:
- Variability in rat molar enamel structure provides new perspectives on amelogenesis.
- Differences in prism patterns may highlight key factors in ameloblast movement control.
